Walgreens announced Wednesday it will acquire 1,900 Rite Aid locations, including stores in New Jersey and in New York. The acquisition brings a two-year process to a close, as the deal lingered while some worried how boosting Walgreens' store count could affect competitive pricing. But Mahmud Hassan, a professor of finance and economics at Rutgers Business School, said that's less of a concern to him, as he predicts the deal will force Walgreens and CVS to compete for customers and slash prices.
